Abstract
Abstract After rugs have been cleaned in place in dwellings using liquids, even though the cleaning operations involve the vacuuming of then dirty cleaning liquids from the rug, considerable moisture is left in the rugs. To remove this residual moisture this rug dryer is centered over a large rug area. Then during drying operations the dryer blower fan draws room air in from above and directs the room air downwardly toward the rug for distribution along the floor and through the rug fibers in multiple directions away from the fan, while being directionally controlled near the rug, below a continuous floating and fluttering layer of an air impervious material extended over a large area of the rug. In a preferred embodiment, the axis of the dryer blower fan is arranged vertically and the fan housing of the blower assembly is mounted above the rug on small diameter legs. Also the fan housing of the blower assembly has a spaced outer ring to which the air impervious material is attached. Primary air is drawn down through the fan and secondary air is drawn down through the surrounding area between the fan housing and the spaced outer ring, supplementing the downwardly moving primary air leaving the fan, thereby creating a large flowing volume of drying air moving below the air impervious material over and through the rug fibers.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
154 words
A rug dryer for placement over large rug areas to further dry rugs, previously cleaned and vacuumed in place, to operate during the drying period without the necessity of a constantly attending operator, comprising: a. a blower assembly arranged for placement over a rug to draw room air in from above over the rug and discharge the room air below into and across the fibers of the rug; and b. a large piece of material arranged around the blower assembly and extending beyond to cover a large rug area, and, during operation of the blower assembly, to be raised throughout its entirety and to be moved in a wave-like motion by the air flow, above the rug area while guiding the blown room air, then serving as the effective drying air, discharged from the blower assembly, to all the outer edges of this large piece of material for its ultimate discharge laden with moisture.
Claim 2
Dependent Claim
154 words
A rug dryer for placement over large rug areas to further dry rugs, previously cleaned and vacuumed in place, to operate during the drying period without the necessity of a constantly attending operator, comprising: a. a blower assembly arranged for placement over a rug to draw room air in from above over the rug and discharge the room air below into and across the fibers of the rug; and b. a large piece of material arranged around the blower assembly and extending beyond to cover a large rug area, and, during operation of the blower assembly, to be raised throughout its entirety and to be moved in a wave-like motion by the air flow, above the rug area while guiding the blown room air, then serving as the effective drying air, discharged from the blower assembly, to all the outer edges of this large piece of material for its ultimate discharge laden with moisture.
Claim 3
Dependent Claim
110 words
A rug dryer, as claimed in claim 1, wherein a ring is spaced from and secured about the blower assembly in the same geometric plane of the blower discharge and the large piece of material is arranged about the ring leaving a space around the blower assembly and between the ring through which room air from above is drawn directly down during operation of the blower assembly, thereby combining, in the same geometric plane, the primary air going through the blower assembly with the secondary air passing alongside the blower assembly, thereby effectively increasing the volume of room air being used to dry the rug area under the rug dryer.
Claim 4
Dependent Claim
33 words
A rug dryer, as claimed in claim 1, wherein the large piece of material is made of impervious material which is light enough to be moved throughout its entirety in a wave-like motion.
Claim 5
Dependent Claim
66 words
A rug dryer, as claimed in claim 1, wherein the blower assembly, in turn, comprises: a. a housing b. legs secured to the housing, placing the housing in a horizontal position, a preselected distance above the rug; c. a frame secured to the housing; d. a motor secured to the frame; and e. a blower fan having a vertical axis supported and driven by the motor.
Claim 6
Dependent Claim
49 words
A rug dryer, as claimed in claim 4, wherein a ring is secured around the housing at a uniform circular space and then the large piece of material is rearranged to be secured to this ring thereby increasing the entry for room air drawn in from above the rug.
Claim 7
Dependent Claim
33 words
A rug dryer, as claimed in claim 5, wherein the large piece of material is made of impervious material which is light enough to be moved throughout its entirety in a wave-like motion.
Claim 8
Dependent Claim
28 words
A rug dryer, as claimed in claim 6 wherein a screen is secured to the housing above the blower fan to prevent unwanted objects from entering the blower.
Claim 9
Dependent Claim
20 words
A rug dryer, as claimed in claim 7, where the motor utilizes electrical power and its axis is arranged vertically.
Claim 10
Dependent Claim
23 words
A rug dryer, as claimed in claim 7, wherein the axes of the motor and blower fan are arranged vertically and in align.
Claim 11
Dependent Claim
77 words
A rug dryer, as claimed in claim 9, wherein the legs are at least three in number and of such height and diameter so as not to restrict the flow of room air, serving as the drying air, while being guided below the large piece of material and through and over the fibers of the rug and ultimately being continuously discharged below the continuous edge of the large piece of material as it undergoes its wave-like motion.
